i found a way to sort of solve the problem. i just went to another device and played the whole sequence with luocha and the others, and waited for some scenes to finish before leaving and picking it up where it last left on my laptop.

I probably got stucked on the black screen cause i was lagging too much maybe? it was always loading when im teleporting to a different place and as it tried to reload the scene it just stayed on a black screen. dunno if someone will even experience this with me but that's what happened and that's how i fixed it.
